V10 MHD Map Discussion
V10 has been released but across some forums there isn't in depth discussion on the performance and the changes in the logs or why. I think the consensus right now is the questioning of the timing dips in the v10 maps and the boost targets at RPMS where it shouldn't be making at a given RPM in the powerband. Shall we discuss and lay out logs. Stage 2+ more in particular.
I dont want to hear "its supposed to be a smoother powerband". Lets just look at the reality instead of what they said was released because the timing pulls are strange. |

If you want to stick to OTS maps, Just try v10 log it and compare with earlier versions to see which one runs better on your car. |

V7 has always been my favourite. Currently trying V10 for fun.

I drove on V7 for a year or so. Then drove v9 for almost a year. When i went back to V7 I loved it so much. Just seems way more consistent and I love the boost curve better. I will be very surprised if I like V10 more than 7.

Here are a couple logs of v10 Stage 2 93oct and a VirtualDyno comparison of v9 vs. v10 with the same car and mods ('09 6MT). Keep in mind the v10 log has about 20F colder IATs, and also remember the VirtualDyno readout is a rough comparison at best but I think shows some useful data for comparison purposes.
I would recommend just trying it yourself and seeing how it works out. I don't have any severe timing drops as others have mentioned at all. https://datazap.me/u/tej98/mhd-v10-s...=0&data=3-4-21 https://datazap.me/u/tej98/mhd-v10-s...og=0&data=3-21 |

Edit* would be cool to see V7 on there too I also spoke to Wedge Performance. They claimed the HP for v10 2+ 93 fbo map is around 400-420 hp at the Crank.

This is why I don't use Virtual Dyno, I don't have a clue how to set it up or use it properly. For a proper comparison conditions have to be very similar on a same road ideally. |

Sorry if it's a dumb question, but is it possible to run V5 E40 with very high octane fuel but no ethanol?
(E40 has an octane rating of about 98)

No....it's not just about octane rating, Stoich (air/fuel mixture) for gasoline and ethanol are different. Don't run an ethanol tune with gasoline.

Yep of course, it was just out of curiousity, because AFR targets of V5 E40 (12.2) seems relatively close with typical octane 100 race gas AFR targets for example, that's why I wondered.

MHD doesn't show it quite right, it multiplies lambda by 14.68 no matter the ethanol content. Lambda 1.00 can be 14.7 for pure gasoline, all the way down to 9.75 for E85. When MHD shows 12.2AFR on e40, for example, it's actually more like 10.3. This would probably pretty much max out fuel trims, run horribly, and throw all sorts of codes

No matters if you run ethanol or race fuel, it will not change the targets. Those targets looks close to what 100 octane race gas targets could be.
